Test::Script::Run - test the script with run SYNOPSIS
use Test::Script::Run; # customized names of bin dirs, default is qw/bin sbin script ./; @Test::Script::Run::BIN_DIRS = qw/bin/; run_ok( 'app_name', [ app's args ], 'you_app runs ok' ); my ( $return, $stdout, $stderr ) = run_script( 'app_name', [ app's args ] ); run_output_matches( 'app_name', [app's args], [ 'out line 1', 'out line 2' ], [ 'err line 1', 'err line 2' ], 'run_output_matches' ); run_output_matches_unordered( 'app_name', [ app's args ], [ 'out line 2', 'out line 1' ], [ 'err line 2', 'err line 1' ], 'run_output_matches_unordered' ); DESCRIPTION
This module exports some subs to help test and run scripts in your dist's bin/ directory, if the script path is not absolute. Nearly all the essential code is stolen from Prophet::Test, we think subs like those should live below "Test::" namespace, that's why we packed them and created this module. FUNCTIONS
run_script($script, $args, $stdout, $stderr) Runs the script $script as a perl script, setting the @INC to the same as our caller. $script is the name of the script to be run (such as 'prophet'). $args is a reference to an array of arguments to pass to the script. $stdout and $stderr are both optional; if passed in, they will be passed to IPC::Run3's run3 subroutineA as its $stdout and $stderr args. Otherwise, this subroutine will create scalar references to pass to run3 instead (which are treated as strings for STDOUT/STDERR to be written to). Returns run3's return value and, if no $stdout and $stderr were passed in, the STDOUT and STDERR of the script that was run. run_ok($script, $args, $msg) Runs the script, checking that it didn't error out. $script is the name of the script to be run (e.g. 'prophet'). $args is an optional reference to an array of arguments to pass to the script when it is run. $msg is an optional message to print with the test. If $args is not specified, you can still pass in a $msg. Returns nothing of interest. run_not_ok($script, $args, $msg) opposite of run_ok get_perl_cmd($script, @ARGS) Returns a list suitable for passing to "system", "exec", etc. If you pass $script then we will search upwards for it in @BIN_DIRS is_script_output($scriptname @args, @stdout_match, @stderr_match, $msg) Runs $scriptname, checking to see that its output matches. $args is an array reference of args to pass to the script. $stdout_match and $stderr_match are references to arrays of expected lines. $msg is a string message to display with the test. $stderr_match and $msg are optional. (As is $stdout_match if for some reason you expect your script to have no output at all. But that would be silly, wouldn't it?) Allows regex matches as well as string equality (lines in $stdout_match and $stderr_match may be Regexp objects). run_output_matches($script, $args, $exp_stdout, $exp_stderr, $msg) A wrapper around is_script_output that also checks to make sure the test runs without throwing an exception. run_output_matches_unordered($script, $args, $exp_stdout, $exp_stderr, $msg) This subroutine has exactly the same functionality as run_output_matches, but doesn't impose a line ordering when comparing the expected and received outputs. last_script_stdout return last script's stdout last_script_stderr return last script's stderr last_script_exit_code return last script's exit code DEPENDENCIES
